WA, ASSIGNOR 0F ONE-THIRD T0 WILLIAM BLACK, or RENWICK, IOWA. EQUALIZER FOR SLIDING noons, DRAWERS, on THE LIKE.

Specification of Letters Patent.

Patented July 30, 1918.

Application filed May 22, 1917. Serial No. 170,335.

To all whom it may concern:

Be it known that I, FREDRIOK A. KING- rrAN, a citizen of the United Stat-es, residing at Renwick, in the county of Humboldt and State of Iowa, have invented new and useful Improvements in Equalizers for Sliding Doors, Drawers, or the like, of which the following is a specification.

This invention relates generally to equal izers which will permit adjustment of a sliding member within its casing without any liability of binding at one end against the wall of its frame and facilitate a quick and easy adjustment thereof.

The primary object of the invention contemplates the provision of a novel construction of equalizers so connected with the facings of the casing and with the movable member, whereby an equal pull will be cxerted on opposite ends of the slidable member and accomplish the opening and closing actions of the movable member without any annoyance of the party operating the same.

With the above and other objects in view, the invention consists in the novel features, details of construction and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawing and pointed out in the appended claim.

Figure 1 is a side elevation of a casing illustrating the equalizer connected thereto for use, the movable member being shown in a partially closed position;

Fig. 2 is a view similar to Fig. 1 illustrating the slidable member in a full closed position;

Fig. 3 is a section taken on line 3-3 of Fig. 1; and

Fig. 4 is a side elevation of a slightly modified form of sliding member, the member in this particular form being shown as an article of furniture such as a drawer or the like.

Referring more particularly to Figs. 1 to' 3 inclusive, A denotes a door casing ineluding spaced parallel rails 6 and re spectively connected together through the medium of a rear and forward cross rail 8 and 9 res ectively. The slidable member indicated y the character 10 and mounted within the frame is illustrated in this particular instance as constituting a slidable door with which my improved equalizer,

denoted generally by the character 11, is connected for tending to exert an equal pull on the opposite ends of the door upon the opening and closing actions thereof, and consequently preventing the derailment of the door by the liability of its catching or binding with the rail 6.

0 this end, use is made of a pair of flexible strands 12 and 13 respectively in the form of cables, ropes or the like. Secured to the inner face of the rear cross rail 8 at points adjacent the ends thereof, I provide a pulley 14, while connected to the confronting face of the front cross rail. 9 and to opposite sides of the line of travel of the door 10, is secured adjacent the ends of the rail, a pair of pulleys 15 and 16 respectively. The pulleys 15 are arranged in alinement to one another and also in substantial alinement with each of the pulleys 14 for a purpose to be hereinafter more fully set forth. Manifestly, these pulleys accommodate the spaced parallel longitudi nal stretches 17 and 18 of the respective flexible strands 13 and 12. and also the horizontal stretches 19 and 20 of the respective parallel stretches 17 and 18. The spaced parallel stretches 17 and 18 are of substantially loop forn'l, the free end of the stretch 17 being connected at the upper extreme end of the door as at 21, while the opposite stretch 18 is terminally connected to the lower end of the door as denoted by the character 22, after which the same are trained over the pulleys 14- and extended to opposite sides of the door and pass over the respective pair of pulleys 15 and 16 to dispose the horizontal portion 19 of the equalizer, not only in spaced parallelism with the faces, but in spaced parallelism with the inner face of the front cross rail 9. For the purpose of operatively connecting the free end of each of the flexible members 11 with the structure, the terminals of the connecting portion 19 are extended in a direction toward the end rail 8 and connected with the inner edge of the door at point inwardly of the point of connection of the spaced parallel stretches of the door, and denoted by the characters 23 and 24.

In the modified form of the invention disclosed in Fi 4 of the drawing, I have illustrated a casing 25 embodying side parallel rails 26 connected to one another through the medium of a rear cross rail 27 and a forward cross rai1 28, andtthe movablemember 29 mounted within the casin for slid ing, movement a drawer. Liiewise, in this form of the invention consists of a pair of flexible strands 30 and 31 respectively, and are so assembled and connected with the drawer to present spaced parallel StIetC-lIQBBQ and 33 of the respective strands 30 and 31. Therefore, the free end of the stretch 32 is connected to the rear face 34 of the movable member 29 at a point adjacent one side face of the movable memher; as denoted by the character 35, while the stretch 33 is connected to the rear face adjacent the oppositeside of the movable member, presenting a pair of spaced parallel loops 36 and 37, by the training of the stretches over the pulleys 38 connected with the rear cross strip 27 of the casing and extending the same in a direction toward the rear strip 28, and thence horizontally oi' the casing as denoted by the chamcters 39 and 40 respectively.

From the foregoing description, taken in connection with the accompanying drawing, the" advantages 'of construction and the method of operation will be readily apparent to those skilled in the art to which the invention relates, and While I have d escribed the principles of operation of the invention together with the device which I the equalizer now consider to be the best embodiment thereof, I desire to have it understood that thedevim shown is 119181 61) lll\1Sblai1iVe,,a/H(l that such changes may be made when de sired as are within the scope of the appended claim.

What is claimed as new, is?

The combination with a frame including a rear rail and spaced forward rails and a member slidablb in the frame and between the forward rails, of pulleys secured to the upper and lower ends ofeach forwardrail, a pulley secured to the upper end of the rear rail on one side of the plane of movement of the member, another pulley secured to the lower end of the rear rail on the opposite side of the plane of movement of the member a flexible connector terminally secured to the member near the lower end and on one side thereof, passed over the lower rear rail pulley, then forwardly and over the lower and upper forward rail pulleys on the same side, and then secured to the rear edge of the member, and a second flexible con neetion secured to the member near the upper end and on one side thereof and trained over the respective pulleys on. that side of the member and terminally secured to the lower edge of the member.

In testimony whereof affix my signature.
